Simulations are performed on a reconfigurable 12-element antenna which produces vertically and horizontally polarized gain patterns and is intended for base station use.
The millimeter wave frequencies being planned for 5G systems pose challenges for channel modeling. At these frequencies, surface roughness impacts wave propagation, causing scatter in non-specular directions that can have a large effect on received signal strength and polarization. To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. Wireless InSite’s diffuse scattering capability is based on Degli-Esposti’s work.
This example analyzes the coupling between four circular patch antennas mounted on the sides of a Boeing 757. The antennas transmit and receive at a frequency of 2.4 GHz. Coupling between each antenna is characterized using XGtd’s S-Parameter output, which can be displayed in the user interface or exported to a v1.1 Touchstone file.
Remcom’s MPI+GPU technology and large memory support are used to simulate an inter-vehicle communication system operating in traffic on a highway. This example demonstrates how massive electromagnetic design problems become tractable while still using the high resolution offered by an FDTD simulation.
